Okay, I see. I'll switch to FB_UDL for now and remove DRM_UDL from my
config.

Is somebody working on porting commit
https://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=8d21547d3c9c3bc653261f26d554cfabc4a083de
 to the DRM_UDL driver?

In Airlie's tree seems to be no commit related to this:

 Hi Thomas,

Hi Bernie!


 We were seeing similar issues in udlfb (the original fbdev version of
 this driver), which were fixed earlier this year by getting all
 rendering operations out of probe/disconnect -- those which might
 trigger fb_defio page faults in an inappropriate context, or be
 long-running. Here's some more detail:

Hi Thomas,

We were seeing similar issues in udlfb (the original fbdev version of this
driver), which were fixed earlier this year by getting all rendering
operations out of probe/disconnect -- those which might trigger fb_defio
page faults in an inappropriate context, or be long-running. Here's some
more detail:
http://plugable.com/2012/06/21/displaylink-usb-devices-on-linux-kernel-3-4-0/comment-page-1/#comment-5896

Unfortunately, I haven't had time to get going with udl myself, so haven't
been able to port and confirm.  Thanks for raising and staying on this.

Best wishes,
Bernie
